Since the amount of information downloaded from the network and created by users on their own cannot be accommodated on the memory embedded in a computer, and removable hard drives and flash drives are expensive, some people prefer to use DVDs, recording video files and music, photographs and documentation on them.
Instructions
Step 1
All DVDs are divided into three types: read-limited, writable, and rewritable. The first are the very finished films sold in video stores. They are purchased for viewing only and are not subject to change. The second type includes DVD-R and DVD + R, the former being compatible with all, even outdated devices, due to its earlier appearance on the market, while the latter is easier to use. Although modern players support both formats.
Step 2
The third type is DVD-RW, DVD + RW, and DVD + RAM. The latter is not known to a wide range of users due to its poor compatibility with household devices and high cost, but it is successful with professionals due to the large number of recording cycles performed on it. While the operation can be repeated 50 times in the first two views, DVD + RAM can be rewritten 5000 times. In addition, all the changes made can be viewed on the monitor in the very process.
Step 3
The disc can be single and double layer, and also have one or two working sides. The simplest disc contains information of 4, 7 GB (although in reality the memory is reduced to 4, 38 GB). The second layer is transparent and invisible to the naked eye. Applied on top, it brings the volume up to 8.5 GB. The other, unoccupied side is for file names. If the disc is double-sided, then on the back it can have one or two layers. In the first case, when there is one layer on both sides, the memory reaches 9.4 GB. The maximum size is 17 GB. There is also a smaller version of the DVD in 1, 4 GB. Its diameter has been reduced, but such a blank is recorded on all DVD drives, just like the full-fledged version.
Step 4
It is believed that the blanks sold in individual packaging are of better quality than those threaded onto a spindle. This is only partly true. A cheap product does not try to imitate an expensive one, while branded models can be manufactured in the same factories as an economy option. For example, Digitech does not have its own production and orders products from Chinese factories that also produce cheap DVDs. In contrast to this brand, Verbatim and DataLife Plus are Mitsubishi Chemical and produce very worthy products. But DataLife, without the word Plus, has the worst quality compared to the previous ones. They have excellent reviews Paste Disc, SONY, but some, according to users, are suitable only as a stand for coffee: Memorex, Imation.
